Clinical manifestations 1. Chronic anxiety (generalized anxiety) (1) Emotional symptoms In the absence of obvious triggers, patients often experience excessive worry, nervousness and fear that do not match the reality of the situation, and such nervousness and fear often have no clear object or content. Patients feel that they are always in a nervous, anxious, fearful, frightened and worried internal experience; (2) vegetative symptoms dizziness, chest tightness, panic, shortness of breath, dry mouth, frequent urination, urgent urination, sweating, tremor and other somatic symptoms; (3) motor restlessness fidgeting, restlessness, irritability, and difficulty in quieting the mind. 2, acute anxiety attack (panic attack, panic disorder) (1) sense of near death or loss of control in normal daily life, the patient is almost like a normal person. Once the attack occurs (some have specific triggering situations, such as closed spaces, etc.), the patient suddenly appears extremely fearful psychologically and experiences a sense of near-death or loss of control; (2) symptoms of the vegetative nervous system appear at the same time, such as chest tightness, panic, dyspnea, sweating, shivering, etc.; (3) generally lasts for a few minutes to a few hours, the attack starts suddenly and the patient is conscious during the attack; (4) it is very easy to misdiagnose the attack. (4) The patient often calls the “120” emergency number and goes to a cardiology emergency room. Although the patient appears to have severe symptoms, most of the relevant tests are normal, so the diagnosis is often unclear. After the attack, patients are still extremely fearful and worried about their condition, so they often go to various departments of major hospitals and do various tests, but the diagnosis cannot be confirmed. Both delayed treatment also caused a waste of medical resources. 3, phobias (including social terror, place terror, specific terror) The core performance of phobias and acute anxiety attacks are the same as panic attacks. The difference is that the anxiety attacks of phobias are caused by certain specific places or situations, and patients do not cause anxiety when they are not in these specific places or situations. Examples include fear of social situations or interpersonal interactions, or fear of specific environments: airplanes, plazas, crowded places. The onset of anxiety in phobias is often predictable, and patients tend to adopt avoidance behaviors to avoid anxiety attacks. 4. In the U.S. diagnostic criteria for mental disorders, anxiety disorders are broad in content, including generalized anxiety, acute anxiety attacks, phobias, post-traumatic stress disorder, acute stress disorder, and obsessive-compulsive disorder.
